Khirki Masjid, 14th century Tughlaq mosque in South Delhi, India

Khirki Masjid is a square-shaped structure from the 14th century that sits on a raised platform and features 81 domes with four corner minarets. Its three exterior walls are covered with numerous windows arranged in grid patterns, allowing light and air to flow through the interior.

A prime minister under Sultan Feroz Shah Tughlaq ordered this building between 1351 and 1354. It was created during a period of growth for the Tughlaq dynasty and reflects their architectural style.

The name Khirki comes from the Urdu word for "window", and the mosque is also called the Mosque of Windows. Its upper floor is pierced by arched windows cut from stone with perforated jali screens. The eastern gate carries the builder's name, Khan-e-Jahan Junaan Shah, and the south gate now serves visitors.

The mosque is located within a densely built village, so reaching it requires walking through narrow streets. It is good to prepare for uneven ground and tight pathways, and to wear respectful clothing.

In 2018, during archaeological works at the mosque, the ASI uncovered a large number of copper coins on the site. An earlier find of 63 coins had been made there in 2003, pointing to long use of the spot.
